Enum FromMessagesError 

#[non_exhaustive]
pub enum FromMessagesError {
    LengthMismatch {
        messages: usize,
        pinned: usize,
    },
}

Returned by ConversationSnapshot::new and History::from_messages when the supplied parallel vectors are inconsistent. Surfaces at restore time so a malformed snapshot fails loudly instead of corrupting state silently.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

LengthMismatch

messages and pinned were not the same length. Both fields carry the observed lengths so callers can report the exact mismatch.

Fields

messages: usize

Observed length of the messages vector.

pinned: usize

Observed length of the pin mask.

Trait Implementations

impl Debug for FromMessagesError

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for FromMessagesError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Error for FromMessagesError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for FromMessagesError

fn eq(&self, other: &FromMessagesError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
